Is astrophotography real? Is that even the right question? Maybe it's better to break things down a bit and answer smaller questions... like are colors real? This is the second part in a series about whether astrophotography is real. We get into Whorfian ideas of cognition, optical illusions, neuroscience and more! Is Astrophotography Real Part 2: Context and Color

@TechnologyConnections 's awesome video about brown: youtube.com/watch?v=wh4aWZRtTwU&t=751s

I made a free SNR app that can help you know how much integration time you need. It's simple to use! Check it out here: deepskydetail.shinyapps.io/Calculate_SNR

Try the sharpening tool I made! Download it from GitHub here:
